Oot 3Step direct cause

OOT 100% three step process (direct cause)
The direct cause of obtaining an item, is the action before obtaining the item, opening chest -> get item, trigger cs -> get item.

When seeing if items are gotten legit we look at the direct cause:

Slingshot
1: Open Chest in Deku Tree
2: Obtain Slingshot

Mirror Shield:
1: Trigger Chest
2: Open Chest
3: Obtain Mirror Shield

Both of these are two intended ways to get the items, if we dive further into the matter and
take a look at item upgrades:


Slingshot 50:
1: Play Game
2: Obtain SeedBag 50


We can skip SeedBag 40 because we only need to obtain the "Best" upgrade the intended way.
"also why only the best upgrade is required is because the game deletes previous upgrades as if they never existed" Zas 2016


So if we go into the Nocturne of Shadows

N64:
1: Have Forest, Fire and Water Medallions and Enter Kakariko from Hyrule field as adult
2: Watch Cutscene/Trigger CS
3: Obtain Nocturne

VC:
1: Wrong Warp from either Deku or DC
2: Watch Half the CS/Trigger CS
3: Obtain Nocturne

We can clearly see here that the step before obtaining the item is the correct way, atleast partly.

The reason RBAing Medalions and Songs aren't allowed. Obtaining the item to RBA does not count as a step
because it's not connected to the obtained items directly.

1: RBA Odd Potions
2: Get Songs & Stones

While this is giving you the songs, the direct cause of getting them is not the intended way.

If we look at Obtaining medallions

1: Activate Warp
2: Watch CS/Skip CS (Which still triggers the CS)
3: Obtain Medalion

We can clearly see that we have triggered the event that gives us the Medalion.

Beating the game:

1: Last stab on ganon
2: Credits
3: The end screen

1: WW
2: Credits
3: The end screen

both of these does indeed start the credits, and does both lead to giving us the end screen.
